a 2 claims. (c1. 10s-7) Y This invention relates to improvements in roofing and siding elements.

It is one of the objects lof this invention to provide an improved roofing andsiding element having water-proofing and bituminous material ap.-

p1ied`to both sides thereof, in which said sides'- are colored differently so that they may be used interchangeably to produce various effects upon the roof.

One lof the novel features of4 the invention re sides in the manner of forming indented definition lines on the elements to create the eiect of individual shingle thereon. If the indented definition lines on one side were directly in line with those on the other side, the material would be considerably weakened along the edges of the figures and its capacity to withstand weather and breakage would be greatly diminished. f

It is therefore an object of this invention to provide a shingle element in which the definition lines on one side are oset with relation to those on the other side, so that the materialwill ,not be unduly weakened by reason of said definition lines.

It is a further object of this invention to provide an 'improved roofing and siding element which is simple in construction, attractive in appearance, and well adapted for the purpose described.

' With the above and other objects 'in View, the. invention consists of the improved roong and siding element, and all itsy pas and combinaj tions, as` set forth in theclaims, and all equivalents thereof. l

In the accompanying drawing. in 1which the samef reference numerals designate the saine parts in all of the. views:

element; and

Fig. 2 is a sectional View taken on line 2-2 of Fig. 1.

Referring to the drawing, the numeral 8 designates the base of the, roong and siding material, which is preferably felt. Each side of the base is coated with a layer of asphalt 9 or other waterproofing material. sprinkledl overv and partially embedded in the'asphalt, on each-side, is a layer of mineralmaterial 10, such asgranulated slate. may be of one color or a combination of colors, and the slate and asphalt on the other side may be of a different color or different combinationpf colors. The roofing and siding elements may be of any desired shape, the drawing illustrating'an The slateand asphalt on one side l element having semi-hexagonal tabs projecting therefrom. f i

In order to complete "the hexagonal gures, indented definition `lines 11 are formedqonl the body of the elements on onejside. I The said lines 6o are preferably produced by applying heat and pressure to depress the surface, or by applying pressure alone while the surface coating is in a semi-liquid state. Similar lines 12 are formed on .the other side of the element, said lines, however, being offset with relation to the linesll; as zlearlyv shown in Fig. 2. Ifvthe lines 11 were directly above the linel 12, there' would be only `a very thin portion of material between, and the roong and siding elements would be dangerous- 70 ly Weak, also. the said lines. By having the vlines offset, however, this objectionable feature is overcome.

Inasmuch as each element .hastwo usable sides, carrying different color effects, theV side of each element may be used whichlbest fits intoA the color scheme which it is desiredto carry out on-the roof. Thus, the roofing contractor is able to carry out awide range of color effects with a much smaller stock of shingle elements than if each element had only one nished side.

Although only on'e form of roong and siding element has been shown and described, it; isto bev understood that the invention comprehends all changes andmodifications as may come with- 35 inthe scope of the claims.

1. A roofing and siding element comprising a fibrous base having a weather protecting coating on both sides thereof, one of said sides hav- 90 ing denition lines formedthereon by indentationo'f the surface coating to a depth not greater/ than the depth of vthe coating to leave the base unaffected, and the other of said sides having similarly formed definition lines of like depth, g5- the denition lines on the two sides forming figures of substantially similar shape and of substantially identical position on the twov sides, the definition lines on one side being oiset with relation to the definition lines on the other side to 10o prevent weakening of the material, and the gure on one Isdebeing smaller in size than in the figure below on theother side by the amount of said offset.

2. A roofing and siding element comprising a fibrous base having a weather protecting coating ofr substantially the lsame thickness as used in* standard practice on b'oth sides thereof, one oi' said sides having definition lines formed thereon PATENT OFFICE l f yus not greater4 than the depth of the coating to leave the base unaffected, and the other of said sidesp having vsimilarly formed definition lines of like depth, the denition lines on the two sides forming figures of substantially similar shape and o1' substantially identical position on the two sides, the denition lines on one side being 'offset with NORMAN P.
